BACKGROUND

Unless otherwise indicated herein, the materials described in this section are not prior art to the claims in this application and are not admitted to be prior art by inclusion in this section.

Mobile computing devices such as smart phones, tablets and laptop computers are ubiquitous. These devices are capable of connecting to networks to download and use digital content, as well as interact with other devices. Users rely on mobile devices and the digital content accessed thereby, for their work as well as leisure activities. However, Wide Area Network (WAN) connections, which provide access to the internet and/or other networks facilitating access to large amounts of digital content, are not always available. For example, WAN connectivity is often unavailable in vehicles such as cars, buses, airplanes, trains and boats, as well as in remote areas and areas of poor wireless transmission. Meanwhile, in many areas lacking WAN connectivity, mobile devices may be able to connect to one or more nearby networks and/or devices.

SUMMARY

The present disclosure describes technologies including devices, methods, and computer readable media relating to contextual use and expiration of digital content. Some example computing devices may comprise receiving devices configured to receive and display digital content from a sponsoring device. Receiving devices may comprise a processor, a memory, a communication device, and an authenticator configured to detect a relationship property defining a relationship between the receiving device and the sponsoring device and to allow and disallow displaying the digital content by the receiving device, based on the relationship property. For example, when the relationship property indicates that the receiving device is one or more of: directly connected to the sponsoring device, connected to a Local Area Network (LAN) comprising the sponsoring device, and within a predefined maximum distance from the sponsoring device, displaying the digital content may be allowed, while conversely, if the relationship property indicates that the receiving device is one or more of not directly connected to the sponsoring device, not connected to a LAN comprising the sponsoring device, and not within a predefined maximum distance from the sponsoring device, displaying the digital content may be disallowed.

The digital content may comprise, for example, an application, a video file, an audio file, a text file, a file stream, or any other type of file. The digital content may comprise a multi-user application that enables interaction between a user of the receiving device and a user of the sponsoring device. The receiving device may be configured send and receive digital content interaction instructions to and from the sponsoring device. The digital content received from the sponsoring device may be encrypted, and the authenticator may be configured to allow displaying the digital content after taking appropriate security measures, for example, validating a decryption key using the relationship property and decrypting the digital content.

In some embodiments, the receiving device may be configured to receive the digital content and the authenticator from a sponsoring device, and to load and execute the authenticator in response to an instruction received from the sponsoring device. In some embodiments, the receiving device may comprise an operating system that includes the authenticator. In some embodiments, the receiving device may be configured to load and execute an auxiliary operating system, and to load and execute the digital content in the auxiliary operating system, in response to an instruction received from the sponsoring device along with the digital content. In some embodiments, the receiving device may be configured to receive, from the sponsoring device, a screen feed comprising the digital content.

The receiving device may comprise an operating system that includes a local marketplace tool configured to discover, aggregate, and display digital content items available from one or more sponsoring devices for which a relationship property defining a relationship between the receiving device and the sponsoring devices allows displaying the digital content items by the receiving device. The receiving device may comprise a payment manager configured to receive payment information in consideration for displaying the digital content by the receiving device. Also, the receiving device may be configured to provide an opportunity to acquire the digital content from a source other than the sponsoring device when displaying the digital content by the receiving device is disallowed.

Some example methods and computer readable media may comprise instructions configured to implement discovering, by a receiving device, digital content available from one or more sponsoring devices, wherein the sponsoring devices are those for which a relationship property indicates that the receiving device is one or more of: directly connected to the sponsoring device, connected to a LAN comprising the sponsoring device, and within a predefined maximum distance from the sponsoring device. The discovered digital content may be aggregated and displayed to a user, and a user selection may be received by the receiving device. A request for the digital content may be sent to the sponsoring device having the selected digital content, and the receiving device may receive the selected digital content from the sponsoring device. An authenticator may detect a relationship property defining a relationship between the receiving device and the sponsoring device providing the digital content and the authenticator may allow and/or disallow displaying a digital content item as described above. The received digital content may be allowed to be displayed by the receiving device so long as the detected relationship property continues to allow such displaying, and periodic relationship property status checks may be made to ensure the relationship property continues to allow such displaying.

Some example receiving devices configured to receive digital content from sponsoring devices may comprise a processor, a memory, a communication device, and a local marketplace tool. The local marketplace tool may be configured to discover, aggregate, and display digital content item information identifying digital content items available from sponsoring devices for which a relationship property allows displaying the digital content items by the receiving device. For example, as introduced above, the relationship property may allow displaying the digital content items by the receiving device when the receiving device is one or more of directly connected to the sponsoring device, connected to a LAN comprising the sponsoring device, and within a predefined maximum distance from the sponsoring device. A receiving device may also comprise an authenticator configured to detect the relationship property and allow or disallow displaying the selected digital content item.

Some example computer readable media having instructions implementing a local marketplace tool may include instructions configured to discover, aggregate, and display digital content item information identifying digital content items available from sponsoring devices for which a relationship property allows such discovery, aggregation, and displaying. For example, when the relationship property indicates that the receiving device is directly connected to the sponsoring device, connected to a LAN comprising the sponsoring device, and/or within a predefined maximum distance from the sponsoring device, the relationship property may allow such discovery, aggregation, and displaying.

Some example sponsoring devices may be configured to send temporary-use digital content to receiving devices. Sponsoring devices may comprise a processor, a memory, a communication device, and a digital content sponsoring service configured to send temporary-use digital content to receiving devices. The temporary-use digital content may comprise digital content that is usable at the computing device, for example, by being displayable and/or executable at the computing device, when a relationship property defining a relationship between the receiving device and the sponsoring device indicates that the receiving device is one or more of directly connected to the sponsoring device, connected to a LAN comprising the sponsoring device, and within a predefined maximum distance from the sponsoring device. Conversely, the temporary-use digital content is not displayable at the receiving device when the applicable relationship between the receiving device and the sponsoring device no longer exists. The sponsoring device may comprise a user device or a server, e.g., a server in a mass transit vehicle, a building server such as a library server, or a private business enterprise server.

In some embodiments, the temporary-use digital content may comprise a digital content item and an authenticator. In some embodiments, the temporary-use digital content may comprise a digital content item and an instruction for the computing device to load and execute an authenticator. In some embodiments, the temporary-use digital content may comprise a digital content item and an instruction for the receiving device to load and execute an auxiliary operating system, and to load and execute the digital content item in the auxiliary operating system, and to optionally also an instruction for the receiving device to load and execute an authenticator in the auxiliary operating system. In some embodiments, the temporary-use digital content may comprise a screen feed comprising the digital content, and the sponsoring device may be configured to open an auxiliary operating system, to load and execute the digital content item in the auxiliary operating system, and to send the screen feed associated with the auxiliary operating system to the receiving device.

Some example methods for providing temporary-use digital content to a receiving device may comprise publishing by a sponsoring device digital content item information identifying one or more temporary-use digital content items, receiving by the sponsoring device a request for a selected temporary-use digital content item, and sending by the sponsoring device the requested temporary-use digital content item to a receiving device. The temporary-use digital content item may comprise digital content that is displayable at the receiving device when a relationship property allows, as described above. Information identifying temporary-use parameters such as any required relationship properties applicable to the digital content may also be published.

Some example computer readable media may comprise instructions providing temporary-use digital content to a computing device, the instructions publishing by a sponsoring device digital content item information identifying one or more temporary-use digital content items, receiving by the sponsoring device a request for a selected temporary-use digital content item, and sending by the sponsoring device the requested temporary-use digital content item to a receiving device. The temporary-use digital content item may comprise digital content that is displayable at the computing device when a relationship property allows, as described above.

DETAILED DESCRIPTION

In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the Figures, may be arranged, substituted, combined, and designed in a wide variety of different configurations, all of which are explicitly contemplated and made part of this disclosure.

The present disclosure is generally drawn, inter alia, to technologies including methods, devices, and/or computer readable media related to contextual use and expiration of digital content. A receiving device may be configured to connect with a sponsoring device having the digital content. A relationship property defines a relationship context between the receiving device and the sponsoring device. The receiving device may be configured to receive the digital content from the sponsoring device and use the digital content so long as allowed, as determined with reference to the relationship property.

FIG. 1 is a diagram illustrating example computing devices 100, 101, 102 connected via a wired or wireless communication link 150, arranged in accordance with at least some embodiments of the present disclosure. Each of computing devices 100, 101, 102 may comprise, inter alia, a processor 210, a memory 220, a communication device 280, a local marketplace tool 104, a sponsoring service 105, an authenticator 106, a Digital Rights Management (DRM) module 107, and a display 108. Computing devices 100, 101, 102 may also comprise various digital content 110, 120, and 130. In some embodiments, digital content 110, 120, 130 on computing devices 100, 101, 102 may form a temporary-use digital content cloud 170. Digital content 110, 120, 130 in temporary-use digital content cloud 170 may be exchanged as temporary-use digital content 160, as described herein.

In some embodiments according to FIG. 1, a first computing device 100 of devices 100, 101, 102 may interact with one or more other computing devices 101 and/or 102, with first computing device 100 in a role of a “receiving device” configured to receive and use digital content, and any one or more of the other computing devices 101, 102 in roles of “sponsoring devices” configured to provide digital content to receiving device 100. Generally speaking, sponsoring devices 101, 102 may deliver digital content 120 to receiving device 100 in the form of temporary-use digital content 160 that may be used by receiving device 100 so long as a relationship between receiving device 100 and sponsoring devices 101, 102 allows. Temporary-use digital content 160 may expire and become inaccessible by receiving device 100 after the relationship between receiving device 100 and sponsoring devices 101, 102 no longer allows, as described herein.

There are various technical options for configuring the technologies disclosed herein. Prior to enumerating example technical options in detail, however, several real-world use case scenarios are presented below to illustrate example deployments of the technologies described herein.

First use case: travelers on a train. A train traveler Maya has Scrabble® installed on her mobile device. There is no internet service available on the train; however there is an available train-wide Wi-Fi service. Maya would like to play with other live players, in this case, her fellow travelers on the train. However, the fellow travelers may not have Scrabble® installed on their own mobile devices, and may not be able to acquire it without internet service. Using the technologies described herein, Maya may sponsor the temporary-use of the Scrabble® application on mobile devices operated by her fellow travelers. Once the train journey is over and the travelers go their separate ways, the temporary-use of the Scrabble® application may expire. The temporary users may be provided with an offer to acquire the game to convert their temporary license into a permanent license.

Second use case: in-flight entertainment system. An airline provides a server that stores a variety of digital content such as games, eBooks, and videos. The server publishes digital content information via an airplane Wi-Fi signal. Passengers may browse and select desired digital content using their own mobile devices, and receive and display selected digital content, in a temporary form, at their mobile devices. The temporary-use digital content expires when the passengers leave the airplane. The temporary users (passengers) may be provided with an offer to acquire the digital content prior to leaving the airplane or thereafter.

Third use case: tour bus. A group of tourists are on a bus in a remote area. The tourists do not have access to their normal digital content stores, such as the iTunes® store or the Android® Marketplace store, and so new applications as well as other digital content such as songs and videos are not accessible. However, collectively the group of tourists has a large and diverse number of digital content items on their various mobile devices. The devices can connect through a local digital content marketplace tool to discover digital content stored on other tourists' devices, and may receive and use such digital content from one another on a temporary basis. Again, the temporary users may also be provided with an offer to acquire the digital content.

Referring again to FIG. 1, each of computing devices 100, 101, 102 may comprise device hardware such as processor 210, memory 220, communication device 280, and display 108. These and other aspects of device hardware are discussed in further detail with reference to FIG. 2.

Any of computing devices 100, 101, 102 may be configured to receive and use digital content from a sponsoring device. In some embodiments, devices 100, 101, 102 may be configured to both receive digital content and sponsor digital content by including for example the device elements illustrated in FIG. 1. In some embodiments, any of devices 100, 101, 102 may be configured to receive and use, e.g., display digital content from a sponsoring device, but not to sponsor digital content, for example by including the device elements illustrated in FIG. 1 except sponsoring service 105. This disclosure uses “displaying” digital content as an example of using digital content, however, it will be appreciated that uses that do not include “displaying” are also within the scope of this disclosure. For example, executing software code included in digital content may or may not include displaying the digital content.

Any of devices 100, 101, 102 may be configured to sponsor digital content. In some embodiments, any of devices 100, 101, 102 may be configured to sponsor digital content, but not to receive and display digital content, for example by including sponsoring service 105 but optionally not including local marketplace tool 104, authenticator 106, and/or DRM module 107. In the case of a server supporting a sponsoring service, a sponsoring device may optionally also not include display 108.

It will be appreciated that digital content may take many forms, and any form of digital content may be used with embodiments of this disclosure. Digital content may for example comprise an application, video file, audio file, image file, file stream, and/or text file, and combinations thereof. Digital content may take the form of an entire digital content “item” such as an entire file, or may comprise some portion thereof such as a stream that includes portions of one or more files, or a segment of a larger digital content item. In some embodiments, digital content may comprise a multi-user application that enables interaction between a user of receiving device 100 and a user of sponsoring device 102. Embodiments may include features facilitating the interaction of the users via the multi-user application, or may leave this aspect to the native operations of operating systems of devices 100, 101, 102, and/or the multi-user application itself.

Receiving device 100 may include authenticator 106 loadable into memory 220 and executable by processor 210. Authenticator 106 may be configured to detect a relationship property defining a relationship between receiving device 100 and sponsoring device 101, and to allow and disallow displaying digital content 120 by receiving device 100, based on a relationship property status. Example relationships definable by relationship properties include: whether receiving device 100 is directly connected to sponsoring device 101, whether receiving device 100 is connected to a LAN comprising sponsoring device 101, or whether receiving device 100 is within a predefined maximum distance from sponsoring device 101. These are example relationships only and it is contemplated that persons of skill in the art will be able to define additional relationships that are workable within the teachings of this disclosure.

In some embodiments, authenticator 106 at receiving device 100 may be configured to detect whether receiving device 100 is directly connected to sponsoring device 101. As used herein, the term “directly connected” refers to a connection between devices that does not involve any intermediate devices. For example, devices 100, 101 may communicate directly by link 150 so long as link 150 does not relay signals from devices 100, 101 through an intermediate device such as a wired or wireless router, prior to signals from receiving device 100 arriving at sponsoring device 101 or vice versa. As the term “intermediate device” is used herein, a device may be characterized as an intermediate device if it is not controlled by receiving device 100 or sponsoring device 101. Based on the preceding statement, any device included within a housing of a receiving device or a sponsoring device would not be considered an intermediate device. Similarly, devices such as wireless cards and the like which may be connected to a receiving device or a sponsoring device via universal Serial Bus (USB) and are controlled by the receiving device or the sponsoring device are not considered to comprise intermediate devices.

Detecting a direct connection may be performed in a variety of technically feasible approaches. In some embodiments, communication link 150 may be configured to allow only direct communications between receiving device 100 and sponsoring devices 101, 102, and authenticator 106 may be configured to detect the direct connection by detecting that link 150 is active and that sponsoring devices 101, 102 associated with digital content received at receiving device 100 remain available via link 150.

In some embodiments, authenticator 106 at receiving device 100 may be configured to detect whether receiving device 100 is connected to a LAN comprising sponsoring device 101. A LAN is defined herein as any network that connects computers and devices in a limited geographical area such as home, school, library, computer laboratory, office building, vehicle such as an automobile, airplane, bus, or train, closely positioned group of buildings, stadium or other area that is for example 5 square kilometers or less in size. A LAN as defined herein may comprise a so-called home network, Wi-Fi network, Bluetooth network, ad-hoc network, Storage Area Network (SAN), campus network, Near Field Communication (NFC) network, Body Area Network (BAN), Personal Area Network (PAN), and any other network that is limited in geographical area, for example 5 square kilometers or less in size. Devices 100, 101, 102 may establish a LAN over communication link 150. Authenticator 106 at receiving device 100 may be configured to detect the existence of the LAN, and to detect that sponsoring devices 101, 102 associated with content received at receiving device 100 remain available via the LAN. Authenticator 106 may be configured to allow loading and executing the digital content 120 in receiving device 100 when a relationship property indicates that receiving device 100 remains connected to a same LAN comprising sponsoring device 101 as a LAN used when first receiving digital content 120 from sponsoring device 101.

In some embodiments, authenticator 106 at receiving device 100 may be configured to detect whether receiving device 100 is within a predefined maximum distance from sponsoring device 101. For example, receiving device 100 may be Global Positioning System-enabled (GPS-enabled) and sponsoring device 101 may share GPS information with receiving device 100, so that authenticator 106 at receiving device 100 can establish its own location as well as a location of sponsoring device 101. Authenticator 106 at receiving device 100 may be configured to detect GPS locations of receiving device 100 and sponsoring device 101, and to compare GPS locations to determine whether receiving device 100 is within a predefined maximum distance from sponsoring device 101. Technologies other than GPS may be used in some embodiments determine location—it will be appreciated that any technologies whether now in existence or as may be developed in the future may be appropriate for some embodiments of this disclosure.

Authenticator 106 at receiving device 100 may be configured to allow displaying digital content 120 by receiving device 100 when the relationship property allows, for example, when receiving device 100 is one or more of: directly connected to the sponsoring device 101; connected to a LAN comprising the sponsoring device 101; and/or within a predefined maximum distance from the sponsoring device 101. Authenticator 106 at receiving device 100 may disallow displaying digital content 120 by receiving device 100 when a relationship property indicates that receiving device 100 is one or more of: not directly connected to sponsoring device 101; not connected to a LAN comprising sponsoring device 101; and not within a predefined maximum distance from sponsoring device 101.

In some embodiments, authenticator 106 at receiving device 100 may be configured to allow and disallow displaying digital content 120 in response to one or more parameters other than a detected relationship property. For example, in some embodiments, the authenticator may be configured to apply one or more of a time limit and a usage count limit, and to disallow displaying the digital content after the time limit or usage count limit has elapsed. In an example scenario, a meeting may be scheduled for a particular time and duration, and at a particular location. The meeting participants (and their receiving devices) may or may not be connected to a same LAN. The context of the meeting may be defined by the location (e.g., GPS co-ordinates), the time, and the duration of the meeting. Digital content may be sponsored by one or more meeting participants for use by the others. The digital content may be accessible only during the meeting and in the meeting location. After the meeting, use of the digital content by the receiving devices may be disallowed, optionally even if a receiving device remains in the meeting location, due to the lapse of the time specified for the meeting. Use of digital content may also be allowed/disallowed according to a usage count, either in combination with restrictions according to time/location/relationship properties, or independently.

In addition to, or in lieu of, allowing and disallowing display of digital content 120 from sponsoring device 101, other forms of digital content consumption may also be allowed and disallowed. For example, authenticator 106 may be configured to allow and disallow audio playback using the techniques described herein.

Allowing and disallowing consumption of digital content 120 by receiving device 100 may be achieved using a variety of technical approaches. For example, in some embodiments, authenticator 106 may be configured to instruct DRM module 107 at receiving device 100 to allow or disallow displaying digital content 120. DRM module 107 may be responsible for ascertaining whether access to particular digital content is permissible, and decrypting digital content using decryption keys when permissible. DRM module 107 may be configured to revoke a decryption key in response to an instruction from authenticator 106. In some embodiments, authenticator 106 may be configured to allow displaying digital content 120 by validating a decryption key using a relationship property, and to disallow displaying digital content 120 by revoking the decryption key.

In some embodiments, a relationship property that indicates that displaying of digital content 120 is allowed may be specified by sponsoring device 101 and/or within temporary-use digital content 160 received at receiving device 100. Receiving device 100 may be configured to allow and disallow displaying digital content 120 by detecting a relationship property specified by the sponsoring device 101 and/or within temporary-use digital content 160.

There are a number of example approaches to enforcing temporary-use of digital content by receiving device 100. First, in some embodiments, receiving device 100 may be configured to natively comprise authenticator 106, e.g., as an application or as a part of an operating system. Sponsoring device 101 may be configured to provide digital content 120 with appropriate encryption and instructions for authenticator 106 at receiving device 100, so that digital content 120 will “expire” or be disallowed by native authenticator 106 once a relationship property is no longer true. In this case, temporary-use digital content 160 may comprise digital content 120 along with instructions for native authenticator 106 at receiving device 100.

Second, in some embodiments, receiving device 100 may receive digital content 120 and authenticator 106 from sponsoring device 101. Receiving device 100 may be configured to load and execute authenticator 106 in response to an instruction received from sponsoring device 101 along with received digital content 120 and received authenticator 106. Authenticator 106 thereafter allows and disallows displaying of digital content 120. In this case, temporary-use digital content 160 comprises digital content 120 along with authenticator 106, and any instructions for loading authenticator 106 as a prerequisite to displaying digital content 120.

Third, in some embodiments, receiving device 100 may be configured to load and execute an auxiliary operating system, e.g., a Virtual Machine (VM), and to load and execute digital content 120 in the auxiliary operating system, in response to an instruction received from sponsoring device 101 along with digital content 120. This third approach may be applied in combination with the first or second approaches described above. This third approach has the advantage of allowing mobile devices having diverse platforms, e.g., Android®, iOS®, and Windows Mobile® platforms, to nonetheless share digital content 120 by employing virtual machines equipped to operate with digital content 120.

Fourth, in some embodiments, receiving device 100 may be configured to receive, from sponsoring device 101, a screen feed comprising digital content 120. In some embodiments, the screen feed may be produced by an auxiliary operating system instance loaded at sponsoring device 101. Receiving device 100 may be configured to send digital content interaction instructions to sponsoring device 101 and sponsoring device 101 may be configured to process receiving device 100 interactions with digital content 120 and update the screen feed accordingly. The screen feed will generally be lost when a communication link between devices becomes inoperable, and authenticator 106 at receiving device 100 may configured to operate in such embodiments as a backup that guarantees expiration of received content, and/or to otherwise limit the use of digital content 120 included in the screen feed at receiving device 100.

In some embodiments, devices 100, 101, 102 may include a local marketplace tool 104. In general, local marketplace tool 104 may be configured to discover, aggregate, and display, at receiving device 100, digital content item information identifying one or more digital content items available from one or more sponsoring devices 101, 102 for which a relationship property defining a relationship between receiving device 100 and one or more sponsoring devices 101, 102 allows displaying the digital content items by receiving device 100, as described above. For example, local marketplace tool 104 at receiving device 100 may discover, aggregate, and display digital content item information identifying digital content in temporary-use digital content cloud 170, in particular digital content 120 and 130, because digital content 110 is already at receiving device 100 and therefore the user of receiving device 100 does not need to be made aware of availability of digital content 110. In some embodiments, local marketplace tool 104 may provide a limited substitute digital content marketplace at receiving device 100 that may lack a broad network connection providing access to large digital content marketplaces such as iTunes® or Android® Market. Digital content available from local marketplace tool 104 may include digital content available from devices to with which receiving device 100 can connect in a particular context, and use of digital content available from local marketplace tool 104 may be limited to the particular context, as defined by a relationship property.

Local marketplace tool 104 may be included as a part of an operating system included in receiving device 100, or may be included in receiving device 100 as a separate, freestanding application. Local marketplace tool 104 may be configured to retrieve, via communication device 280, a selected digital content item, e.g., digital content 120. Local marketplace tool 104 may be configured to load an authenticator and/or other elements allowing receiving device 100 to temporarily access retrieved digital content 120. For example, local marketplace tool 104 may be configured to load and execute authenticator 106 as a precondition to displaying digital content 120. Authenticator 106 may in some embodiments be received from sponsoring device 101 along with digital content item 120, as described above. Local marketplace tool 104 may be configured to load and execute an auxiliary operating system, and to load and execute a digital content item with the auxiliary operating system, as discussed above. Local marketplace tool 104 may additionally or alternatively be configured to connect receiving device 100 with a screen feed from sponsoring device 101, the screen feed comprising digital content 120.

In embodiments where a receiving device 100 comprising local marketplace tool 104, authenticator 106 may be configured to detect a relationship property defining a relationship with sponsoring device 101 in response to user selection of a digital content item from digital content item information displayed by local marketplace tool 104 at receiving device 100. Authenticator 106 may be configured to allow or disallow displaying the selected digital content item according to whether the relationship property allows or disallows displaying the selected digital content item, as described above.

With or without local marketplace tool 104 in receiving device 100, authenticator 106 may be configured to detect a relationship property during display of a digital content item, and authenticator 106 may be configured to allow or disallow further displaying the selected digital content item according to whether the relationship property allows or disallows displaying the selected digital content item. For example, authenticator 106 may be configured to make periodic detection attempts to validate the relationship property, so long as temporary-use digital content is displayed.

In some embodiments, local marketplace tool 104 may be configured to receive and display price information with digital content item information. Local marketplace tool 104 may be configured to provide a UI configured to receive payment information. Local marketplace tool 104 may be configured to queue and/or execute a payment in consideration for temporary-use of exchanged digital content. For example, temporary-use of digital content may comprise “renting” digital content. In such embodiments, owners of digital content may associate temporary-use price metadata with digital content, and local marketplace tool 104 may be configured to extract and display the temporary-use price metadata.

In some embodiments, local marketplace tool 104 may be configured to provide an opportunity to acquire digital content from a source other than a sponsoring device. For example, local marketplace tool 104 may be configured to provide a UI prompting purchase or other acquisition of digital content, after receiving device 100 is no longer permitted to use the digital content under its temporary-use license, i.e., when displaying the digital content by receiving device 100 is disallowed. In some embodiments, the UI prompting purchase may be provided when digital content, such as a video, was not watched through to the end, or for example if a game was not played through the end thereof. In some embodiments, a UI prompting purchase may be provided when digital content, such as a game or other application, was used under a temporary license at least some predefined threshold amount, as defined by time or number of interactions. In some embodiments, payment and/or acquisition prompt features described above in connection with local marketplace tool 104 may be provided in another element such as a payment manager and/or authenticator 106.

Turning now to a discussion of aspects of sponsoring devices, a computing device such as, for example, device 101, may be configured as a sponsoring device 101 by including, inter alia, digital content sponsoring service 105. Digital content sponsoring service 105 may be configured to publish digital content item information identifying one or more temporary-use digital content items, such as digital content item 120. Sponsoring service 105 may be configured to receive a request for a selected temporary-use digital content item. Sponsoring service 105 may be configured to send, in response to the received request, temporary-use digital content 160 to receiving device 100, wherein temporary-use digital content 160 comprises selected digital content 120 that is displayable at receiving device 100 when a relationship property defining a relationship between receiving device 100 and sponsoring device 101 allows. For example, as described above, the relationship property may allow displaying digital content 120 when it indicates that receiving device 100 is one or more of: directly connected to sponsoring device 101, connected to a LAN comprising sponsoring device 101, and within a predefined maximum distance from sponsoring device 101. A relationship property may disallow displaying digital content 120, and digital content 120 may be not displayable at receiving device 100, when the relationship property defining a relationship between receiving device 100 and sponsoring device 101 indicates that receiving device 100 is one or more of: not directly connected to sponsoring device 101, not connected to a LAN comprising sponsoring device 101, or not within a predefined maximum distance from sponsoring device 101.

In some embodiments, sponsoring service 105 may be configured to publish price information with digital content item information. Prior to sending digital content to a receiving device, sponsoring service 105 may be configured to provide a UI configured to receive payment information. Sponsoring service 105 may be configured to queue and/or execute a payment in consideration for temporary-use of digital content. For example, temporary-use of digital content may comprise “renting” digital content. In such embodiments, owners of digital content may associate temporary-use price metadata with digital content, and sponsoring service 105 may be configured to extract and display the temporary-use price metadata, and to process digital content rental payments.

In some embodiments, sponsoring device 101 may comprise a mobile device that is configured for personal use, such as a small form-factor device that can be carried in a pocket, briefcase or purse. In other embodiments, sponsoring device 101 may comprise a larger form-factor server that is not configured to be carried about. For example sponsoring device 101 may comprise a server in a mass transit vehicle, a building server such as a library server, or a private business enterprise server. A server may be dedicated to providing temporary-use digital content. In a mass transit setting, temporary-use digital content may be provided for entertainment of passengers, with an option to purchase content upon arrival at a destination. In a library server, temporary-use digital content may be usefully limited to patrons that are physically within a library. Similarly, temporary-use digital content may be usefully limited to occupants of any common location such as a building or park. In a private business enterprise server, certain proprietary or confidential temporary-use digital content may be advantageously restricted so that employees may access digital content on business premises, and may not access digital content from locations outside business premises.

Sponsoring device 101 may be configured to arrange temporary-use digital content 160 according any configuration discussed herein. For example, temporary-use digital content 160 may comprise digital content item 120 and authenticator 106, so that receiving device 100 loads authenticator 106 along with digital content item 120. Temporary-use digital content 160 may comprise digital content item 120 and an instruction for receiving device 100 to load and execute an auxiliary operating system, and to load and execute the digital content item 120 in the auxiliary operating system. Temporary-use digital content 160 may comprise a screen feed comprising digital content 120, and sponsoring device 101 may be configured to open an auxiliary operating system, to load and execute digital content item 120 in the auxiliary operating system, and to send the screen feed associated with the auxiliary operating system to receiving device 100.

FIG. 3 is a schematic diagram illustrating example interactions between receiving device 100 configured to receive and display digital content 120, and sponsoring device 101, arranged in accordance with at least some embodiments of the present disclosure. Receiving device 100 includes local marketplace tool 104, digital content 120 received from sponsoring device 101, authenticator 106, DRM module 107, a player 350 and display 108. Sponsoring device 101 includes sponsoring service 105 and digital content 120. In some embodiments, devices 100, 101 may also include any of the other features disclosed herein. FIG. 3 provides a general view of an example interaction between receiving device 100 and sponsoring device 101. Further details and elements involved in interactions between receiving device 100 and sponsoring device 101 are described in connection with FIG. 4 and FIG. 5, respectively.

In accordance with FIG. 3, example methods may comprise a discovery operation 301 including discovering, by receiving device 100, digital content available from one or more sponsoring devices 101, wherein the available sponsoring devices are those for which a relationship property indicates that receiving device 100 is one or more of: directly connected to sponsoring device 101, connected to a LAN comprising sponsoring device 101, and within a predefined maximum distance from sponsoring device 101. In some embodiments, discovery 301 may include one or more of publication of digital content information by sponsoring device 101, and discovery, aggregation and display of published digital content by local marketplace tool 104. In some embodiments, specialized tools or software need not be involved in discovery 301. For example, a message board may allow users to post and discover digital content available from sponsoring devices.

A user of receiving device 100 may select discovered digital content, and local marketplace tool 104 may be configured to initiate a request/payment operation 302 in response to the user selection. When payment is not required, local marketplace tool 104 may be configured to request the selected digital content from a sponsoring device having the selected digital content. When payment is required, local marketplace tool 104 may present a payment UI to a user at receiving device 100, receive payment information via the payment UI, and send received payment information to sponsoring device 101.

In operation 303, sponsoring service 105 may be configured to send requested digital content 120 to receiving device 100. Sponsoring service 105 may be configured to send digital content 120 in the form of temporary-use digital content, for example by including such additional executable code with digital content 120 as necessary to ensure that digital content 120 is disabled when a relationship property is no longer valid, or by sending digital content 120 in such a form that it automatically becomes unavailable or inaccessible when the relationship property is no longer valid. Embodiments of temporary-use digital content may for example include authenticator 106 along with digital content 120. Embodiments of temporary-use digital content may provide prerequisite instructions along with digital content 120, the prerequisite instructions for example requiring operation of authenticator 106 at receiving device 100 in order to access digital content 120.

In operations 304-309, authenticator 106 may be configured to detect a relationship property defining a relationship of receiving device 100 with sponsoring device 101 and to allow and/or disallow displaying digital content item 120 as described above. For example, authenticator 106 may be configured to detect in operation 304 whether the relationship property continues to allow displaying digital content 120. In an example in which the relationship property allows continued displaying of digital content 120, authenticator 106 may be configured to allow DRM module 107 to display digital content 120 in operation 305, e.g., by providing DRM module 107 with an updated decryption key indicating that the relationship property remains valid. Alternatively, in some embodiments authenticator 106 may be configured to allow DRM module 107 to display digital content 120 in operation 305 by not taking action to disallow the displaying of digital content 120, or by sending a status update to DRM module 107. Similarly, authenticator 106 may be configured to detect in operation 306 whether the relationship property continues to allow displaying digital content 120. If the relationship property continues to allow, authenticator 106 may be configured to allow DRM module 107 to continue to display digital content 120 in operation 307.

Similarly, authenticator 106 may be configured to detect in operation 306 whether the relationship property continues to allow displaying digital content 120. However, in this example detection in operation 306 results in a determination that the relationship property disallows displaying digital content 120 in operation 306. Therefore, authenticator 106 may be configured to disallow displaying digital content 120 in operation 309, for example by revoking a decryption key used by DRM module 107, or otherwise notifying DRM module 107 that digital content 120 has been disallowed. DRM module 107 may be configured to enforce termination of displaying digital content 120 by player 350 and/or display 108, and to either delete or prevent subsequent unlicensed access to digital content 120 by receiving device 100.

There is little distinction left between hardware and software implementations of aspects of systems; the use of hardware or software is generally (but not always, in that in certain contexts the choice between hardware and software may become significant) a design choice representing cost vs. efficiency tradeoffs. There are various vehicles by which processes and/or systems and/or other technologies described herein may be effected (e.g., hardware, software, and/or firmware), and that the preferred vehicle will vary with the context in which the processes and/or systems and/or other technologies are deployed. For example, if an implementer determines that speed and accuracy are paramount, the implementer may opt for a mainly hardware and/or firmware vehicle; if flexibility is paramount, the implementer may opt for a mainly software implementation; or, yet again alternatively, the implementer may opt for some combination of hardware, software, and/or firmware.

The foregoing detailed description has set forth various embodiments of the devices and/or processes via the use of block diagrams, flowcharts, and/or examples. Insofar as such block diagrams, flowcharts, and/or examples contain one or more functions and/or operations, it will be understood by those within the art that each function and/or operation within such block diagrams, flowcharts, or examples may be implemented, individually and/or collectively, by a wide range of hardware, software, firmware, or virtually any combination thereof. In one embodiment, several portions of the subject matter described herein may be implemented via Application Specific Integrated Circuits (ASICs), Field Programmable Gate Arrays (FPGAs), digital signal processors (DSPs), or other integrated formats. However, those skilled in the art will recognize that some aspects of the embodiments disclosed herein, in whole or in part, may be equivalently implemented in integrated circuits, as one or more computer programs running on one or more computers (e.g., as one or more programs running on one or more computer systems), as one or more programs running on one or more processors (e.g., as one or more programs running on one or more microprocessors), as firmware, or as virtually any combination thereof, and that designing the circuitry and/or writing the code for the software and/or firmware would be well within the skill of one of skill in the art in light of this disclosure. In addition, those skilled in the art will appreciate that the mechanisms of the subject matter described herein are capable of being distributed as a program product in a variety of forms, and that an illustrative embodiment of the subject matter described herein applies regardless of the particular type of signal bearing medium used to actually carry out the distribution. Examples of a signal bearing medium include, but are not limited to, the following: a recordable type medium such as a floppy disk, a hard disk drive, a Compact Disc (CD), a Digital Video Disk (DVD), a digital tape, a computer memory, etc.; and a transmission type medium such as a digital and/or an analog communication medium (e.g., a fiber optic cable, a waveguide, a wired communications link, a wireless communication link, etc.).

Those skilled in the art will recognize that it is common within the art to describe devices and/or processes in the fashion set forth herein, and thereafter use engineering practices to integrate such described devices and/or processes into data processing systems. That is, at least a portion of the devices and/or processes described herein may be integrated into a data processing system via a reasonable amount of experimentation. Those having skill in the art will recognize that a typical data processing system generally includes one or more of a system unit housing, a video display device, a memory such as volatile and non-volatile memory, processors such as microprocessors and digital signal processors, computational entities such as operating systems, drivers, graphical user interfaces, and applications programs, one or more interaction devices, such as a touch pad or screen, and/or control systems including feedback loops and control motors (e.g., feedback for sensing position and/or velocity; control motors for moving and/or adjusting components and/or quantities). A typical data processing system may be implemented utilizing any suitable commercially available components, such as those typically found in data computing/communication and/or network computing/communication systems. The herein described subject matter sometimes illustrates different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely examples and that in fact many other architectures may be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively “associated” such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality may be seen as “associated with” each other such that the desired functionality is achieved, irrespective of architectures or intermediate components. Likewise, any two components so associated may also be viewed as being “operably connected”, or “operably coupled”, to each other to achieve the desired functionality, and any two components capable of being so associated may also be viewed as being “operably couplable”, to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to: physically connectable and/or physically interacting components; wirelessly connectable and/or wirelessly interacting components; and/or logically connectable and/or logically interacting components.

With respect to the use of substantially any plural and/or singular terms herein, those having skill in the art may translate from the plural to the singular and/or from the singular to the plural as is appropriate to the context and/or application. The various singular/plural permutations may be expressly set forth herein for sake of clarity.

It will be understood by those within the art that, in general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). It will be further understood by those within the art that if a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, those skilled in the art will recognize that such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, and C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended in the sense one having skill in the art would understand the convention (e.g., “a system having at least one of A, B, or C” would include but not be limited to systems that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”

While certain example techniques have been described and shown herein using various methods, devices and systems, it should be understood by those skilled in the art that various other modifications may be made, and equivalents may be substituted, without departing from claimed subject matter. Additionally, many modifications may be made to adapt a particular situation to the teachings of claimed subject matter without departing from the central concept described herein. Therefore, it is intended that claimed subject matter not be limited to the particular examples disclosed, but that such claimed subject matter also may include all implementations falling within the scope of the appended claims, and equivalents thereof.
